gitlab ci 集成jacoco-Go服务器开发

在GitLab项目中创建一个.gitlab-ci.yml文件。
将以下代码插入.gitlab-ci.yml文件中：

image: openjdk:8-jdk

stages:
  - build
  - test

before_script:
  - apt-get update && apt-get install -y ant

build:
  stage: build
  script:
    - ant jar

test:
  stage: test
  script:
    - ant test
  artifacts:
    reports:
      junit: junit.xml
  coverage: '/Total coverage\: ([0-9]+\.[0-9]+)/'

jacoco_report:
  stage: deploy
  image: alpine
  script:
    - apk add --no-cache openjdk8
    - java -jar /jacoco/lib/jacococli.jar report /jacoco/coverage.exec --classfiles /src/test/java/ --html /reports/jacoco
  dependencies:
    - test
  when: always
  needs: []
  artifacts:
    reports:
      browse: reports/jacoco/index.html
    paths:
      - reports/

接下来需要在构建前下载Jacoco，并且为测试任务配置Jacoco。在build:和test:阶段添加以下命令：

build:
  stage: build
  script:
    - wget https://repo1.maven.org/maven2/org/jacoco/jacoco/0.8.0/jacoco-0.8.0.zip
    - unzip jacoco-0.8.0.zip -d ~/jacoco
    - ant jar

test:
  stage: test
  script:
    - wget https://repo1.maven.org/maven2/org/jacoco/jacoco/0.8.0/jacoco-0.8.0.zip
    - unzip jacoco-0.8.0.zip -d ~/jacoco
    - ant test

最后，为了在GitLab CI界面中查看Jacoco测试覆盖率报告，需要修改.gitlab-ci.yml文件中的jacoco_report:阶段。将以下代码插入到该阶段：

jacoco_report:
  stage: deploy
  image: alpine
  script:
    - apk add --no-cache openjdk8
    - java -jar /jacoco/lib/jacococli.jar report /jacoco/coverage.exec --classfiles /src/test/java/ --html /reports/jacoco
  dependencies:
    - test
  when: always
  needs: []
  artifacts:
    reports:
      browse: reports/jacoco/index.html
    paths:
      - reports/

这样就可以在GitLab CI界面中查看Jacoco测试覆盖率报告了。
